This is a beautiful, big, brightly banded malachite cabochon pendant in sterling silver, made in Mexico in the 1970's-1980's. The sterling chain is 19" long and the oval pendant is 2 1/2" long which includes the bail. The gorgeous stone measures 26mm x 28mm. The chain and pendant are both marked for 925 sterling silver, and the pendant is marked Made in Mexico. It is in excellent condition, and has not been polished so it has a nice, warm patina. You can see what looks like a tiny scratch on the stone in the pictures, but it is not visible "in person", so it must be extremely faint. It weighs 30 grams.
